sAsH-FASTENER.

SPECIFICATION forming part of Letters Patent NO. 778,276, dated December 27, 1904.

Applicationled June 22, 1904. Serial No. 213,710.

To all whom, it may concern:

Be it known that I, JAMES DoBBs SANFORD, a citizen of the United States, residing at Winchell, in the county of Brown and State of Texas, have invented a new and useful Sash- Fastener, of which the following is a specification.

This invention relates to an improved sashfastener, 'and has for its object the production ofa simple, inexpensive, and efcient device of this character by means of which the window-sash may be securely locked in adjusted plosition and effectually prevented from ratt ing.

The invention consists in the construction and novel combination andv arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims 4hereto appended, it beingl understood that various changes in form, proportions, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advanl lock or fastener detached. F ig. 4 is a front elevation of a portion of the rack detached.

Similar numerals of reference-indicate corresponding parts in all the figures of the drawlngs.

1 designates a window frame or casing of the ordinary construction, 2 the sash slidably mounted therein, and 3 my improved fastener.

The fastener consists of a shell or casing 4, preferably stampedA from a single piece of metal and formed with side iianges' and end anges 6, the latter being provided with perforations for the reception .of screws or similar fastening devices 7 by means of which the fasteners may be secured in position on the window-sash. Slidably mounted in alined openings 8, formed in the opposite side walls 0f the casing and preferably at a point adjacent one end of the latter, is a locking-bolt 9, said bolt being adapted to engage any one of a series of notches or recesses 10 in a metal plate or bar11, secured in any suitable manner to the window frame or casing, as shown. The rear edge of the plate 11 is curved upwardly. and outwardly, forming bearing-surfaces 12 between the several notches or recesses, and against which the end of the bolt rests and is guided to the desired notch in adjusting the sash. The bolt 9 is normally held in engagement with the locking-notches by means of aspring 13, one end of which passes through a `vertical opening 14 vin said bolt,

the opposite end thereof being supported in a bracket 14', riveted or otherwise rigidly secured to the shell or casing. The bracket 14 is provided with laterally-extending ears or lugs 15, having apertures 16 formed therein for the reception of the spring 18, said apertures being arranged out of alinement with each other, so as to cause the walls-of said apertures to firmly grip the end of the spring and prevent accidental displacement of the same. v

Pivoted within the shell or casing is a bellcrank lever 17, oneend of which is provided with a handle 18, which passesthrougha slot 19 in the casing 5. The opposite end of the lever 17 is provided with a laterally-extended lip or lug 20, adapted to engagethe spring 13 when the handle is depressed and withdraw the bolt from engagement withthe notches in l the plate 11, as will be readily understood.

In operation when it is desired to raise or lower the sash the handle 18 is depressed, thereby withdrawing the bolt from the locking recesses or notches and permitting the sash to be adjusted to the desired position. When the handle is released,'the bolt will automatically engage the notches, thereby securely locking the sash and eifectually preventing rattling of the same.

The fastener may be secured to either side of the window-sash, and, if desired, the bolt may be mounted in the upper portion of the shell or casing instead of the lower part thereof, in which event the operating-lever will be elevated to retract the bolt.

Having thus described the invention, what is claimed is 1. In a device of the class described, a casing the side Walls of which are provided with alined openings, a bolt slidably mounted in said openings, a spring engaging said bolt, and a bell-crank lever the short arm of which is provided with a laterally-extending lip adapted to engage the spring for reciprocat- 'ing the bolt.

2. In a device of the class described, the combination With a plate, one edge of Which s bent upwardly and outwardly and provided with a series of spaced bolt-receiving notches, of a casing, the side Walls of Which are provided with alined openings, u bolt slidztbly mounted in seid openings and adapted to engage the locking-recesses, u spring disposed Within the casing :tud engaging the bolt, und a bell-crank lever pivoted to said casing :uid adapted to engage the spring for retructing the bolt.

In testimony that I cluim the foregoing :Ls my own I have hereto uliixed my signature in the presence of two witnesses.
